  • What is the primary cell type in dense regular connective tissue?
    Fibroblast is the major cell type in dense regular connective tissue.
  • Describe the fiber arrangement in dense regular connective tissue.
    Fibers, primarily collagen, are arranged in parallel order to resist tensile stress in one direction.
  • What is the main function of dense regular connective tissue?
    It attaches muscles to bones or other muscles (tendons) and attaches bone to bone (ligaments), resisting tensile stress.
  • Where is dense regular connective tissue commonly found?
    Found in tendons, ligaments, and aponeuroses.
  • How are collagen fibers arranged in dense irregular connective tissue?
    Collagen fibers are irregularly arranged to provide strength in multiple directions.
  • What is the function of dense irregular connective tissue?
    It withstands tension and provides structural strength.
  • Where is dense irregular connective tissue located?
    Located in fibrous capsules of organs and joints, dermis of skin, and submucosa of digestive tract.
  • What fibers form the network in reticular connective tissue?
    A network of reticular fibers forms the framework.
  • What is the primary function of reticular connective tissue?
    It supports immune cells and other cell types in lymphoid organs.
  • Where is reticular connective tissue found?
    Found in lymph nodes, bone marrow, and spleen.
  • Describe the appearance of adipose connective tissue cells.
    Closely packed adipocytes with nuclei pushed to the side by large fat droplets.
  • What are the functions of adipose connective tissue?
    Provides energy storage, insulation, and protection.
  • Where is adipose tissue commonly located?
    Located under skin, around kidneys and eyeballs, within abdomen, and in breasts.
  • What distinguishes elastic connective tissue from other connective tissues?
    Contains a high proportion of elastic fibers allowing tissue recoil.
  • What functions does elastic connective tissue serve?
    Allows recoil after stretch, maintains pulsatile blood flow, and enables lung recoil after inspiration.
  • Where is elastic connective tissue found?
    Located in large arteries, some ligaments, and walls of bronchial tubes.
  • What is the matrix composition of hyaline cartilage?
    Firm matrix with collagen fibers produced by chondrocytes.
  • What are the functions of hyaline cartilage?
    Supports and reinforces structures, serves as cushioning, and resists compressive stress.
  • Where is hyaline cartilage located?
    Found in embryonic skeleton, ends of long bones, costal cartilages, nasal, tracheal, and laryngeal cartilages.
  • How does elastic cartilage differ from hyaline cartilage?
    Elastic cartilage has a firm matrix with prominent elastic fibers in addition to collagen.
  • What is the function of elastic cartilage?
    Provides flexibility and shape to structures.
  • Where is elastic cartilage found?
    Located in the external ear (pinna) and epiglottis.
  • Describe fibrocartilage matrix and function.
    Matrix with collagen fibers; provides tensile strength and shock absorption.
  • Where is fibrocartilage located?
    Found in intervertebral discs, pubic symphysis, and discs of knee joint.
